Hi Tommy,
Thanks for your reply.
It is sure that you can perform full restore from incremental backup. Also
please notice restore from an incremental backup is a little different
with restore from full backup. To restore data from an incremental backup,
you must have the most recent full backup and each subsequent incremental
backup set available. Then during the restore process, you should check the
checkbox in front of those backup files.
The advantage is that it will save the time which backup process cost and
the disk space. Because incremental backup only backup those files which
had been changed but not the full data.
About the disadvantage comparing with SBS backup, which I can image, is
that you need to plan the backup strategy as you need and configure backup
schedule manually.
I would like to suggest that you perform a incremental backup and restore
on some test file as a test at first.
If there are anything unclear, please feel free to let me know.
Have a nice day :-)
Best regards,
Gary Wang(MSFT)

| Thank you Gary for your reply. I would appreciate clarification of your
| suggestion.
|
| My understanding is that SBS backup creates a single .bkf file that could
be
| used to completely restore (bare metal restore) my SBS server in the
event of
| a catastrophic failure by simply re-installing Windows and then using the
SBS
| Restore function using my .bkf file.
|
| If I start using NTbackup with differential or incremental backups as you
| indicated in option 3, would the bare metal restore process be the same
as if
| I had used SBS backup? Would I be able to completely restore my server
(AD,
| Exchange settings and information store etc) by using this option? Would
| there be any other disadvantages or differences to using NTbackup instad
of
| SBS backup if I had to do a full server restore?
